Three-Dimensional Block Matching Using Orthonormal Tree-Structured Haar Transform for Multichannel Images [PDF]
Multichannel images, i.e., images of the same object or scene taken in different spectral bands or with different imaging modalities/settings, are common in many applications.

An Improved BM3D Algorithm Based on Image Depth Feature Map and Structural Similarity Block-Matching [PDF]
We propose an improved BM3D algorithm for block-matching based on UNet denoising network feature maps and structural similarity (SSIM). In response to the traditional BM3D algorithm that directly performs block-matching on a noisy image, without ...

Despeckling of Ultrasound Images Using Block Matching and SVD in Sparse Representation [PDF]
This work proposes a novel scheme for speckle suppression on medical images acquired by ultrasound sensors. The proposed method is based on the block matching procedure by using mutual information as a similarity measure in grouping patches in a ...

Sequential Blocked Matching [PDF]
We consider a sequential blocked matching (SBM) model where strategic agents repeatedly report ordinal preferences over a set of services to a central planner. The planner's goal is to elicit agents' true preferences and design a policy that matches services to agents in order to maximize the expected social welfare with the added constraint that each

De-Speckling Breast Cancer Ultrasound Images Using a Rotationally Invariant Block Matching Based Non-Local Means (RIBM-NLM) Method [PDF]
The ultrasonic technique is an indispensable imaging modality for diagnosis of breast cancer in young women due to its ability in efficiently capturing the tissue properties, and decreasing nega-tive recognition rate thereby avoiding non-essential ...

Dual-Attention-Based Block Matching for Dynamic Point Cloud Compression [PDF]
The irregular and highly non-uniform spatial distribution inherent to dynamic three-dimensional (3D) point clouds (DPCs) severely hampers the extraction of reliable temporal context, rendering inter-frame compression a formidable challenge.

MR Image Reconstruction Using Block Matching and Adaptive Kernel Methods. [PDF]
An approach to Magnetic Resonance (MR) image reconstruction from undersampled data is proposed. Undersampling artifacts are removed using an iterative thresholding algorithm applied to nonlinearly transformed image block arrays.

New Selective Block Matching Searching Algorithm Based on Block Discriminator Values For Motion Estimation [PDF]
In this paper, a new, fast and efficient selective block matching algorithm based on block discriminator values is suggested. The searching scheme consists of three stages: block discriminator values calculations, open full window then cascaded selection
